Answer:
(4) 266 moles
Explanation:
We have Dinitrogen Pentoxide N2O5
6.41*10^25 molecules are given
No of Moles of N2O5 = 
= 
= 106.5 mol
Now using Unitary Method
2 Mole of Nitrogen pentoxide require 5 mole of Oxygen to form N2O5
1 mole of N = 
In 106.5 mole of N = 
= 266.25 mole
So, 6.41*10^25 molecules of N2O5 will require 266.25 mole of Oxygen atoms.

Al(CN)3 =Aluminum Cyanide
hope it helps :)
Answer:
Its either glucose or protien
Explanation:
Answer:
114.4 grams of P₄O₁₀
Explanation:
P₄ + 5O₂ → P₄O₁₀
50 grams of P₄ are (50 g / 123.88 g/m) = 0.403 moles
Ratio is 1:1 so 0.403 moles of phosphorus can produce the same amount of P₄O₁₀.
Molar mass P₄O₁₀ = 283.88 g/m
0.403 moles . 283.88 g/m = 114.4 g
